java.lang.IllegalArgumentException: List has more than one element #38

Closed gchristov closed 3 years ago

gchristov commented 3 years ago

I'm testing out the plugin to potentially use it in an app with lots of sub-modules and libraries. Following the README, I have added the plugin and config to the build.gradle to the main app module as I would like to check all app dependencies. However, this is throwing an error List has more than one element which seems to come from here:

  val resolvedFiles = pomConfiguration.allModuleDependencies.flatMap { it.allModuleArtifacts }.map { it.file }
  val pomDocument = factory.newDocumentBuilder().parse(resolvedFiles.single())

in dependencyGraph.kt

I noticed that the info in README suggests that we should be adding the plugin to leaf modules. After doing so, I got the correct output for that individual module and artifacts.json was generated properly. I then added it to another separate module which worked again for that specific module but it created a second artifacts.json specific to that module.

Is there a way to setup the plugin so that it can traverse the entire dependency graph of the project and generate a single artifacts.json for all dependencies in the app? (Apologies if I missed something in the README file)

An example of how it's used in cashapp would be much appreciated!

Somehow your Maven repository is returning two files when looking up a pom. Run with --info and you'll be able to see the Maven coordinates which are causing the problem. And if they're a public dependency, to share them here. If it's private, you'll have to try and replicate the setup in a fixture test with a similar artifact setup that causes Gradle to resolve two (or more) files for the pom.

I tried again with v1.1.0 of the plugin which seems to have resolved the issue! I managed to get the artifacts.json file generated for my :app module by running ./gradlew app:licensee. Thanks for looking into it 👍
